Bug Fixes

Fixed require() checks that reference columns from data(). Before, a .require() condition that used model.data() columns could emit a warning even when the input rows satisfied the requirement. Now PyRel warns only when the condition is actually violated.
Fixed std.math.isclose() so that it correctly evaluates an absolute-tolerance comparison. Before, std.math.isclose() could silently produce the wrong result in filters and selections.
Fixed lookups on subtypes such as Manager, a subtype of Employee. Before, a lookup such as Manager.approves_budget could use the wrong relationship or raise a type mismatch. Now PyRel resolves the subtype before resolving the relationship.
Improved reserved-name diagnostics for concepts and tables. Before, if you used a reserved name such as alias, new, or require, the error could be unclear or point to the wrong place. Now PyRel points the error at the call site. For reserved table column names, the message also tells you to use table indexing, such as table["alias"].

Deprecations

The use_direct_access config option is now deprecated in favor of the reasoners.backend setting.

Preferred configuration:

connections:
  snowflake:
    account: my-account
    user: my-user
    password: ${SNOWFLAKE_PASSWORD}
    database: MY_DB
    schema: PUBLIC
    warehouse: COMPUTE_WH

reasoners:
  backend: direct_access

Deprecated configuration:

connections:
  snowflake:
    account: my-account
    user: my-user
    password: ${SNOWFLAKE_PASSWORD}
    database: MY_DB
    schema: PUBLIC
    warehouse: COMPUTE_WH

use_direct_access: true

Existing use_direct_access entries still work, but PyRel warns that they are deprecated and converts them to reasoners.backend: direct_access. For details, see Configure reasoners.
